Mechanical energy = potential energy + kinetic energyThe ball is on the ground so has no potential energy.
M.E = K.EM.E = 1/2 mv²M.E = 1/2 x 1 x 2²M.E = 2 J

Nataly_w [17]

Answer:

F= 0

Explanation:

This exercise we use Newton's second law,

            F = m a

in this case as the speed is constant the acceleration is zero therefore the force is zero.

Change we can solve it using Newton's first law, which states that every vehicle remains still or with constant speed if there is no extensive outside acting on it

We see that with any of the two forms the sum of the applied forces is zero

                     ∑ F = 0
